As shown in the drawings, there is a toilet bowl IQ having an annularconduit I I at the upper end thereof, with the conduit having aplurality ,of spaced parts or opening I2 at the lower side thereof. Anapron I3 extends downwards and 4m forwardly from the un der, side ofconduit II and its free end extends below the level of the waternormal-1y contained in the bowl II]. A normal discharge pipe I-Iislocated at the rear and may be connected to the usual sewer pipe. Thebowl 45 Ifl has a plurality of reservoirs I5, I6, I1, I8, I9

were located below the lower level of said con-.

duit -II and formed in two batteries and it is a single-unitarystructure which may be composed of porcelain or the like. Thesereservoirs are 50. closed and connected in series by conduits 2I, 22, 1'3; 24 and 25 which are located near the bottoms of these'reservoirs. Aninlet passage 26 near the upper end of chamber I5 is adapted to beconnected to the city line 21. A vertically disposed opening 28 at thebottom of the chamber I5 extends downwardly to a horizontally disposedconduit 29 connecting the same to a vertically and centrally disposedconduit 30 having its other end opening into the annular chamber I I.This continuous passageway 28-49-30 is the flush 5 line from the chamberI5 to the distributing annular chamber II.

Located inthe chamber I5 is a flush valve resting on a somewhatresilient rubber bushing- 3| extending into passage 28 and forming awater 10 tight seal therewith. A metallic expansion bushing 32 is forcedinto the bushing 3I and forces the side of' bushing 3| to bear snuglyagainst the passageway 28. The bushing 3! has an enlarged upper end witha shoulder seating on'the bottom 15 of chamber I5 and litharge or otherappropriate material is applied to the lower face of the shoulder andsides of the bushing so that a water tight seal is formed between thebushing and lower part of chamber I5 at opening 28. The upper 20 orenlarged end of the bushing 3| forms a seat for the valve.

The novel valve comprises a one piece housing member of bronze or thelike including a cylindrical member 3| and box like projection 34 25communicating therewith. The upper end of the housing is in the form ofa cover 35 integral with the sides of the box projection 34 and thecylindrical member 33. And, a guide member 36 is integral with the cover35 and has a portion 30 thereof spaced from the upper face of the cover35. Both the. cover 35. and member 36 have centrally disposed andvertically aligned cylindrical openings adapted to accommodate acylindrical valve stem 31 having a pair of spaced ears 5 38, at itslower end. The valve 39 has a bearing face whose contour is a part of asphere so that the same may readily close the flush passage 28, byautomatically finding its own bearing surface on the upper edge of therubber bushing 3|. The 40 upper part of the valve has a pluralityofstops 58 to limit the amount of upward travel of the valve and it alsohas a tongue II located between the cars 38. A pin 42 passes through theears 2-8 and tongue 4| andthe size of the opening in the tongue IIthrough which pin 42 passes is somewhat greater than the diameter of thepin 32 so that the valve 39 is loosely and freely pivoted thereon. Theupper and outer end of box' projection 34 has a pair of upstanding ears43.

A loosely fitting plate gate 44 with a plurality of openings 45 thereinnear. the lower edge thereof and a weighting projection 46 on the outerface thereof has a tongue 41 located between the cars 33 and projectingupwardly thereabove. A pin 48 extends through the ears 43 and tongue 41.The diameter of the opening in the tongue 41 through which pin 48extends is slightly greater than the diameter of pin 48 so that the gate44 is freely pivoted thereon.

A bar 49 has one end located and loosely fitting between the cover 35and guide 36 and has an opening therein aligned with the verticalopenings in the cover 35 and guide 36. The stem 31 which passes throughthese three openings is of such a diameter that it passes freely throughthese three openings, and the diameter of the opening in the bar 49 issuch that there is a real loose fit between the stem 31 and bar 49 forthe reasons hereinafter fully explained. The other end of bar 49 is in.the form of a pair of cars 50 between which the tongue 41 is located anda pin 52 extends through the ears 50 and tongue 1, with the size of theopening in tongue 41 through which pin 52 passes being slightly greaterthan the diameter of pin 52. A demountable cylindrical casing 5I havinga slot therein to accc-mmodate the bar 49 is mounted on the cover 35 bypressing the same over the projection thereon and is maintained inposition by friction aliough it may be keyed or bolted or in some othermanner secured thereto.

A yoke 55 has a threaded nut 56 making a threaded connection with thethreaded upper end of stem 31. The upper end of easing 5I has a pair ofdiametrically opposed vertical slots accommodating a shaft having aneccentric 51 for actuating the yoke 55 upon rotation of eccentric 51.The shaft has guide projections 58 for maintaining the eccentric 51 inproper position with respect to the upper cross arm of yoke 55. On oneend of said shaft is U member 59 whose legs are located in the openingsof an H element 60 of the mechanism for actuating said shaft. The sizeof the opening defined by the yoke 55 is sufficient so that said shaftmay be removed therefrom. A cover plate 6I caps the upper end of thecasing and it has a right hand threaded member 62 integral therewith andextending upwardly and centrally thereof.

A hand screw member 63 whose lower half is interiorly threaded toaccommodate the right hand threads of member 62 and whose upper half isinteriorly threaded to accommodate left hand threads makes threadedconnections with member 62 and a left hand screw threaded member 64having a positioning and locking element 65 integral therewith. Asshown, by rotating the hand screw in one direction, the bearing element65 may be brought downwardly towards the cover 6|, and if it is rotatedin the other direction, the bearing element is moved away from the cover6| and towards the top of chamber I5. This particular construction maybe used to demountably mount the valve in the chamber I5. The hand screwis so rotated that the bearing element 65 is forced against the top faceof chamber I5 to maintain the valve in position.

An enlarged opening 10 extends from the outside of the unit to thechamber I 5. This provides a passageway through which the valve may beinserted and mounted in the chamber I 5. A cover plate 1| encloses thisopening and is maintained in position by bolts 12, there being a gasket13 located between the plate H and the porcelain unit in order toprovide a water tight seal. At the center of the cover plate andintegral therewith there is a housing 14 through which passes a shaft 15having the H member 60 integral therewith at the inner end thereof.

Secured to the outer end of shaft 15 is a handle 16 for rotating theshaft. A water tight joint between the housing 14 and shaft 15 ismaintained by packing 11 located at the inner end of housing 14 andpressed forwardly by a bushing 18 actuated by spring 19 held in positionby member 88.

A spring is mounted on the outside of the porcelain unit and under thehandle 16 and urges the handle 16 upwardly against the stop 8|. Inpractice the toilet and valve may be assembled either in the shop or atthe place of use. If it is assembled in the factory, the assembly may betaken to the place of use and be mounted therein in a very short periodof time. The unitary, single element may have a passageway extendingfrom an inner wall thereof to the passage 29. Connected to thispassageway 90 and to the discharge pipe is a valve chamber having aninclined seat 9|. A gate valve 92 is loosely pivoted at the upper end ofsaid chamber and is adapted to close the passageway between the passage29 and discharge pipe upon being forced over to the inclined seat 9|.The rear of the unit may be placed flush against the wall of thebathroom with the valve 82 of the city water line 21 being located in avertical slot 83 at the rear of the unit. This line is connected to theinlet 26 communicating with the chamber I5 and the discharge pipe I4 isconnected to the normal sewer pipe. Thus, all the installation iscompleted now merely by affixing the porcelain unit to the flooring ifdesired.

In operation with the valve 82 open, water flows in the closed chamberI5 and then to the other closed chambers I6, I1, I8 and I9. Watercontinues flowing into these chambers until the pressure of the aircushions formed in these chambers prevent the fiow of any more waterinto them from the city line. Thus, each chamber contains water underpressure. When the handle 16 is pushed downwardly, the shaft 15 isrotated. The shaft 15 rotates the H member 60 which is integraltherewith.

The 'H member 60 upon rotation causes the U member 59 to rotate. And,rotation of U 59 causes rotation of eccentric 51. Rotation of eccentric51 bearing against the upper cross arm of yoke 55 and causes the yoke 55to be lifted. As the yoke is moved upwardly by the eccentric 51, thestem 31 .and the valve 39 are carried upwardly therewith until the stops40 strike the bottom of cover 35. With the valve 39 spaced from its seatof bushing 3 I, the Water under pressure in the six chambers flows intoand through the bushing 32. Because of the pressure of this water on theoutside of the plate gate the gate is subjected to a force in thedirection of arrow A and this force is transmitted to the bar 49 whichis now subjected to a force in the direction of arrow B and towards theopening in the side of chamber I5 to maintain by friction the stem 31 inupper position whereby the valve 39 is maintained in open position evenafter the lever 16 is released and returned to its original position.When the valve 39 is in open position, the water is automatically forcedfrom the chambers through the bushings 3I and 32 then through theconduits 2829-30 of the flush line to the distributing chamber II, thenthrough the ports I2 and bowl ID to the discharge outlet I4. After apredetermined quantity of water, say 3-8 gallons, has flushed the bowl,the pressure of the water on gate 44 has so decreased, that its forcetransmitted to bar 49 is insufficient to hold the stem 31 in its upperposition and consequently 11 valve ahd sten'i together with the'yoke'xaiitoa' flly" d op ttP-thiroriginfl positions. #The tle 31-fromthechambers in series now osed;'-th*waterfrom the "city line"ke'epseii ring uritilthe original pressure again builds v Briewater-=irom='-the cityline enters the chambers even when the flushdischarge takes pI-aceP The -vaIVe 82 is not closed at any time exceptwhen the toilet is to be disconnected W Tliu's th' pivoted gate 46controlsthe position of tn valvaaonce it"israised.'
